Mapping xylem failure in disparate organs of whole plants reveals extreme resistance in olive roots

Rodriguez‐Dominguez, C. M., Carins Murphy, M. R., Lucani, C. and Brodribb, T. J. (2018), Mapping xylem failure in disparate organs of whole plants reveals extreme resistance in olive roots. New Phytol, 218: 1025-1035. doi:10.1111/nph.15079

The capacity of plant species to resist xylem cavitation is an important determinant of resistance to drought, mortality thresholds, geographic distribution and productivity. Unravelling the role of xylem cavitation vulnerability in plant evolution and adaptation requires a clear…

Coordinated plasticity maintains hydraulic safety in sunflower leaves

Cardoso AA, Brodribb TJ, Lucani CJ, DaMatta FM, McAdam SAM. Coordinated plasticity maintains hydraulic safety in sunflower leaves. Plant Cell Environ. 2018. https://doi.org/10.1111/pce.13335

The air‐seeding threshold water potential establishes a hydraulic limit on the ability of woody species to survive in water‐limiting environments, but herbs may be more plastic in terms of their ability to adapt to drying conditions. Here we…

Optical Measurement of Stem Xylem Vulnerability

Timothy John Brodribb, Marc Carriqui, Sylvain Delzon, Christopher Lucani (2017) Optical Measurement os Stem Xylem Vulnerability. Plant Physiology Jul 2017, pp.00552.2017; DOI: 10.1104/pp.17.00552

The vulnerability of plant water transport tissues to a loss of function by cavitation during water stress is a key indicator of the survival capabilities of plant species during drought. Quantifying this important metric has been greatly advanced…

Visual quantification of embolism reveals leaf vulnerability to hydraulic failure

Brodribb, T. J., Skelton, R. P., McAdam, S. A. M., Bienaimé, D., Lucani, C. J. and Marmottant, P. (2016), Visual quantification of embolism reveals leaf vulnerability to hydraulic failure. New Phytol, 209: 1403–1409. doi:10.1111/nph.13846

Summary Vascular plant mortality during drought has been strongly linked to a failure of the internal water transport system caused by the rapid invasion of air and subsequent blockage of xylem conduits. Quantification of this critical process is…
